(Updated at 3:35 p.m) After a controversial on-time start that led to a treacherous morning on local roads and sidewalks, Arlington Public Schools is not taking any chances tonight.

Both parents and school bus drivers had trouble getting to school this morning on the roads. According to an APS spokesman, 12 out of around 160 school buses became stuck due to slippery road conditions, and one bus was involved in a “very minor” crash. The spokesman did not have an exact tally of how many buses were late arriving to school

“Our drivers are instructed to drive slow and take all precautions when driving,” said Frank Bellavia.

Following the morning mess, APS canceled all after school and evening activities. The school system announced the cancellations in a tweet just after 1:30 p.m.

While most of the frozen precipitation is over for Arlington, there are still a number of concerns for this evening, including remaining snow on local roads and a possible re-freeze overnight.

More from VDOT:

A mixed bag of precipitation is affecting much of the Commonwealth Thursday, and Virginia Department of Transportation (VDOT) crews are responding to adverse road conditions where needed. Snow, sleet, and heavy rain are expected across Virginia through the afternoon and overnight hours.

Some portions of Virginia are experiencing the first taste of winter in the 2018-2019 season. In affected regions, VDOT crews are deployed to treat roads to melt icy areas. Icy conditions could cause downed trees and debris in roadways. Travelers should exercise caution during the afternoon rush hour and overnight, as road conditions may be wet and slushy.

Portions of the state are experiencing heavy rain. Crews are monitoring road conditions and responding to reports of high water and debris in roadways.

Motorists are encouraged to closely monitor travel conditions in local areas and adjust travel as needed. In wet and icy conditions, allow extra time to reach destinations, lower speed and keep a safe distance from other vehicles.

Another concern: the potential for flooding as a result of melting snow and heavy rain. Arlington and much of the rest of the region is currently under a Flood Watch.

It was an exceptionally rainy summer in the D.C. area, but Arlington County was nonetheless able to complete all of its planned street paving.

“Arlington completed all planned paving projects on October 5, with slurry seal completed on October 19,” Arlington Dept. of Environmental Services spokeswoman Kathryn O’Brien tells ARLnow.com. “The County paved 86.3 lane miles or 390 blocks this year and filled approximately 2,650 potholes.”

By contrast, the Town of Vienna reported earlier this week that it was unable to complete $100,000 worth of paving this year due to inclement weather.

Arlington has been playing catch-up on street paving over the past few years after paving as few as 25 lane miles per year around the turn of the decade, leading to a deterioration of local road conditions.

As Arlington has been drenched by unrelenting rain over these last few months, with totals setting all manner of records for the the D.C. region, local bars and restaurants haven’t exactly been flooded with business.

Owners at a variety of Arlington eateries, particularly those with outdoor patios or beer gardens, say August and September have been especially challenging months when it comes to convincing patrons to brave the elements.

And considering that the Washington area has seen the fourth-highest rain total for any September on record, and D.C.’s rainfall has even managed to outpace notoriously soaked cities like Seattle and London so far this year, those struggles are far from surprising.

“It’s been hard, for sure,” Scott Parker, the co-owner of local bars like Ballston’s A-Town and Clarendon’s Don Tito, told ARLnow. “Rain doesn’t exactly make people want to go out. August is one of the slowest months for most restaurants and bars in the area as is. Last thing you need is for it to be rained out.”

Curt Large, the owner of Rosslyn’s Continental Beer Garden, says things have been especially challenging for his establishment, which “lives and dies with the weather.” Though he also owns the adjacent Continental Pool Lounge, and often encourages patrons dodging raindrops to head indoors there, he says the inescapable fact is that “many, if not, most of the beer garden’s customers are looking to sit outside.”

“In July, we actually had higher sales than last year, but in August and September we’ve had rain on many Thursday and Fridays, by far our biggest nights, and our sales are down for this period more than 25 percent versus last summer,” Large said.

Ryan Cline, the general manager of Ballston’s Rustico, lamented that the rain “has taken away some of the last remaining weeks we have to use the patio sections on either side of the restaurant,” as well as the small beer garden the restaurant opens on weekends.

Considering that Rustico has “one of the largest outdoor patio sections in the area,” in Cline’s estimation, the weather has eliminated one of the restaurant’s distinguishing factors for customers.

All that being said, of course, Arlington restaurateurs say rain is part of the business, even if these last few weeks have been more brutal than usual. As Devin Hicks, the co-owner of Westover Market and Beer Garden, puts it: “It’s the weather, so what are you going to do?”

“Being in business for nine years, we’ve learned to roll with the punches,” Hicks said.

Hicks added that, like Large, having an indoor “beer haus” helps give customers another option when the rain picks up. He’s also erected canopies throughout the establishment’s beer garden, which have proven “clutch.”

Luckily, Hicks said that the “support from the neighborhood has been amazing,” even with the constant showers.

Similarly, Cline added that “it has been our local troopers really carrying the burden” over the wettest months, dubbing many of Rustico’s guests “fiercely loyal.”

There is one small bit of good news, however — this weekend’s forecast is looking like a far cry from the past weeks’ downpours.

“It sounds like the weekend is going to be a picturesque early fall weekend of weather,” Hicks said. “We keep pouring great brews no matter what Mother Nature throws at us.”

Arlington and much of the D.C. region is under a Flood Watch today as another big batch of rain moves into the area.

With the ground already saturated, any significant rainfall can cause ponding or even more serious flooding.

Repair work is set to start soon on some large holes that opened up in front of a Rosslyn condo complex.

Several large pits have marked the lawn and front driveway of the Atrium Condominiums, located at 1530 Key Blvd, for the last few weeks. But George Pace, general manager of the Atrium Unit Owners Association, says he should have workers repairing the damage sometime in the next four to six weeks.

Pace says the holes, which are each several feet deep, were the result of the complex’s storm drain collapsing, even though neighbors initially feared they were sinkholes caused by the rain that soaked Arlington last month.

“The storm drain was over 35 or 40 years old,” Pace told ARLnow. “It just got corroded and collapsed… it doesn’t affect the building structure or anything else like that.”

Pace says it’s taken the condo complex some time to work with its insurers and review bids from potential contractors, but he’s confident the situation will be resolved soon.

In the meantime, the complex’s front driveway, including some portions not visibly impacted by the holes, will remain closed.

Forecasters are warning of the possibility of “multiple rounds of torrential rainfall” that could result in flash flooding given the already-saturated ground.

(Updated at 6 p.m.) The relentless rain soaking Arlington is prompting some serious flooding in the Waverly Hills neighborhood, and now people living there are pressing the county for help.

Tom Reich, a longtime homeowner in the area, told ARLnow that many of his neighbors along the 4000 block of 18th Street N. experienced serious flooding starting two weeks ago, on May 22. He also sent along the above video, showing water reaching high enough to partially submerge some cars parked on 18th Street N. and carry away some recycling bins.

“Many houses had their garages, basements, and cars flooded, sustaining many thousands of dollars in damage,” Reich wrote in an email.

Reich added that similar floods have plagued the neighborhood several times over the years — in 2001, 2003, 2006 and 2013 — and the Waverly Hills Civic Association convened a meeting on May 31 with county officials to address the problem. Reich says many residents urged the county to construct stormwater management improvements, but they didn’t get much in the way of good news on that front.

“The upshot was that the county told us our need is real and acute, but the money is not currently there in the capital budget to execute the projects,” Reich wrote. “Needless to say, the Waverly Hills residents are now in the beginning stage of a campaign to highlight the threat to our homes presented by the county’s failure to act on its own plan.”

Reich points out that a variety of projects designed to manage flooding in the Spout Run watershed, where the neighborhood is located, have gone unfunded in recent years.

The county’s Capital Improvement Plan passed ahead of fiscal year 2013 included funding for four different sewer projects in the area — but Reich says those were never completed and the next CIP, passed by the County Board two years later, includes no mention of them.

County Manager Mark Schwartz’s proposed CIP, which details construction projects running from fiscal year 2019 through 2028, also includes some funding for stormwater management in other parts of the county, but Reich and his neighbors are frustrated that the spending plan doesn’t call for more construction around Waverly Hills.

Staff with the county’s Department of Environmental Services completed preliminary work on the projects Reich referenced after the 2006 flooding, according to county spokeswoman Jennifer Smith. Yet she says that work “identified significant challenges and costs to upgrade the system, as the current system traverses more than a dozen private properties.”

DES spokeswoman Katie O’Brien adding that the county is “still pursuing” those projects, yet noted that “technical challenges and funding remain an issue.”

Schwartz has certainly warned of the county’s fiscal challenges as he’s unveiled this year’s construction plan, thanks to Arlington’s increasing obligations to fund the Metro system and shrinking commercial tax revenues.

However, Smith would caution that “while greater capacity in the storm sewer would alleviate flooding concerns, there is no system which can guarantee elimination of flood risk to flood-prone properties.”

Arlington County is among the areas under a Flash Flood Watch Thursday afternoon through early Friday morning.

Forecasters say slow-moving storms may develop and drop several inches of rain in a short period of time.
